CLARK B. HALSTEAD ANB JAMES A. CARPENTER, OF MARION, lOHIO.

LOGI-SAWING MACHINE.

.To dll whom it may concern:

Be it known that we, CLARK B. HALSTEAD and JAMEs A. CARPENTER, ofMarion, in the county of Marion, and in the State of Ohio, have inventedcertain new and uset'ul Improvements in Log-Sewing Machines; and we dohereby declare that the following is afull, clear, and exact descriptionthereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon, making a part of thisspecification.

This invention relates to ciel-tain improvements in log-saws; and it hasfor its object to provide an apparatus which may be cheaply constructed,which will be durable and not liable to get out of order, and which maybe readily and conveniently'operated by one person. These objects weattain by the apparatus illustrated in the accompanying drawings, inwhichV I Figure 1 represents a perspective view of the apparatus entire,and Fig. 2 a detached view of the guide for guiding the free end of thesaw.

The letter A indicates the frame of the machine, and is composed of theinclined beams a ci. Between the upper parts of the beams a', which areconnected at the top andbottom by means oi the cross-pieces b, isjournaled the upper end of a swinging bar or sweep, B, whichis adaptedto swing between the beams a.. To the lower` end of the said bar B ispivoted a head, D, by means ot' the segmental connections d and thepivot-pin e.

The letter E indicates a loosely-connected bar, which is located betweenthe beams a and extends toward the front ends of the same. The front endof the bar is provided with a hanger, e', which has a vertical slot, h,and 'riction-wheel'i near its lower end, to guide the' free end of thesaw. rIhe rear end ot' the saw is secured to the pivoted head D, so asto bc moved back and forth by the oscillation of the bar B.

The letter F indicates two prongs at the front of the beams a, which areinserted in the log to be cut, and serve to hold the forward ends of thebeams securely in place.

G indicates a pair of tongs or bent leversV fulcrumed to the forward endof one of the beams a at one side, and connected by linksH SPECIFICATIONforming part of Letters Patent No. 251,872, datedJanuary 3, 1882.

Application ilcd September 28, 1881.

(No model.)

to a bar or rod, I, extending backward to the operator, the` said barhaving serrations or teeth adapted to engage a staple, M', driven intoone of the beams a, by which the tongs Gr are made to clamp and securethe machine to the log. These levers or tongs serve to cla-mp theapparatus to the log, and act in conjunction with the prongs to hold theforward end of the apparatusto its work.

The letter K indicates two curved braces for strengthening theapparatus. L indicates a handle attached to the rods M, which aresecured to the sweep B. Y l

The operation ot' the above invention will be 65 readily understood from`the above description. The forward end ot' the apparatus is secured tothe log, as set forth, the rear end resting upon the ground. The saw isthen adjusted in its guide, and by means ot' the handle and 7o swingingbeam B is traversed back and forth over the log.

The apparatus may be arranged to suit the size of' the operator bychanging the height of the handle, so that it can be used by a grownperson or child, which is done by changing the respective lengths of thepieces M M which form the handle, making their point of union higher orlower, as the case may be..

Havingv thus described our invention, what 8c we claim, and desire tosecure by Letters Patent, is-

In combination with the supporting-frame, constructed as described, andprovided with i prongs to enter the log, the'oscillating sweep, 85carrying a saw working through a suitable slot in a hanger secured to abar loosely connected to the supporting-frame and against africtionroller mounted in an opening in said hanger,

andthe tongs and their operating mechanism, 9o

adapted to work in connection with the prongs on the frame to hold thelog, substantially as specified. In testimony whereof we affix oursignatures,

in presence of two witnesses, this 21st day ot' 95 September, 188i.
